I have a new BES Version: 5.0.1.13 installed on my Windows 2003 SP2 server. It is running 19 users successfully. However it is installed on SQL Server 2008 Enterprise Evaluation Edition which will expire soon. I know I can "down grade" (switch editions) to SQL 2008 Express with Advanced Services pretty easily.

Is that an appropriate version of SQL Server for BES?

Also, in our previous BES 4.1.4 (professional) we had to install user licenses (CALs) for each user. This new version does not require them? Is that correct? We had a consultant assist with install and they claim the CALs are no longer needed per Blackberry?! We are running the 19 users with no issues, but it has only been 2 weeks.
